Each side of the island offers a distinct dive environment with plunging walls and shallow outcrops all within easy distance. This is one of the benefits of coming to Rarotonga because when the conditions are bad on one side, dive sites on the other side will be calm. Visibility can range from 25m on a bad day, right up to 60m or 70m.

The naturalist will see a huge variety of fishlife including colourful parrot fish, wrasses, lionfish, grouper, angel fish, surgeons and more. Sharks, turtles and rays frequent particular sites and for those who are lucky enough, humpback whales may cruise overhead or be seen breaching the surface of the water.

Rarotonga offers caverns and swimthroughs, while divers offer a good chance to search for lionfish and giant moray. When available, the southern passages offer a fascinating experience - huge gashes in the reef between the lagoon and the outer ocean can be up to a few metres wide and over 20m deep. Rorotonga also offers epic drop offs from 30m. Night diving couldn't be easier with great visibility, no currents and smooth surfaces.
